template<typename T>
bool	KIGEOM::PointsAreInSameDirection (const VECTOR2< T > &aPointA, const VECTOR2< T > &aPointB, const VECTOR2< T > &aFrom)
	Check that the two given points are in the same direction from some other point.
bool	KIGEOM::SegIsInDirection (const SEG &aSeg, const VECTOR2I &aDirection)
	Determine if a segment's vector is within 90 degrees of a given direction.
bool	KIGEOM::PointProjectsOntoSegment (const VECTOR2I &aPoint, const SEG &aSeg)
	Determine if a point projects onto a segment.
double	KIGEOM::GetLengthRatioFromStart (const VECTOR2I &aPoint, const SEG &aSeg)
	Get the ratio of the vector to a point from the segment's start, compared to the segment's length.
double	KIGEOM::GetProjectedPointLengthRatio (const VECTOR2I &aPoint, const SEG &aSeg)
	Get the ratio of the vector to a point projected onto a segment from the start, relative to the segment's length.
const VECTOR2I &	KIGEOM::GetNearestEndpoint (const SEG &aSeg, const VECTOR2I &aPoint)
	Get the nearest end of a segment to a point.
VECTOR2I	KIGEOM::RoundGrid (const VECTOR2I &aVec, int aGridSize)
	Round a vector to the nearest grid point in any direction.
VECTOR2I	KIGEOM::RoundNW (const VECTOR2I &aVec, int aGridSize)
	Round a vector to the nearest grid point in the NW direction.
VECTOR2I	KIGEOM::RoundSE (const VECTOR2I &aVec, int aGridSize)
	Round a vector to the nearest grid point in the SE direction.
